Meghan Markle and Prince Harry will spend the night before their wedding in separate country house hotels.
The American star will be with her mother Doria Ragland at the Cliveden House Hotel, on the National Trust's Cliveden Estate in Taplow, Berkshire.
Groom Harry will be 15 miles away at the Dorchester Collection's Coworth Park in Ascot, close to the Guards Polo Club, with his best man and brother the Duke of Cambridge.
Kensington Palace said: "On the night before their wedding, Prince Harry and Ms Meghan Markle will stay at separate hotels in the Windsor area."
With just days to go until the royal wedding on Saturday, the palace also announced the couple's first official engagement as a married couple.
Three days after they wed, the prince and his new bride will honour the Prince of Wales by attending a garden party at Buckingham Palace.
The event - The Prince of Wales's 70th Birthday Patronage Celebration - will see Ms Markle attend her first ever royal garden party in the grounds of the Queen's London residence.
Harry and Ms Markle will join Charles and Camilla at the event on
Tuesday May 22.
Clarence House said: "The event will celebrate The Prince of Wales'
Patronages and Military affiliations as well as others involved in
charities supported by the Prince."
A number of cadets and emergency services personnel who were first
responders after the bombing at Manchester Arena on May 22 2017 will also attend the garden party.
The Cliveden House website describes how the hotel has hosted "powerful personalities, debaucherous parties and scandalous affairs" for more than 350 years.
It was built in 1666 by the 2nd Duke of Buckingham as a gift to his mistress.
The privately owned Grade 1 listed stately home is surrounded by 376 acres of National Trust grounds
Coworth Park in Ascot describes itself as the "scenic route to five-star bliss," so it would appear Harry could be having a sedate night before his wedding.
The hotel's website adds: "Coworth Park offers idyllic relaxation in many guises, from a rural detox to an indulgent, romantic escape.
"Here you'll find an experience to refresh every sense within our welcoming oasis of calm."
The accommodation once featured in the popular TV talent show X Factor, and William and Harry are likely to know the hotel well as the royal brothers play on its polo grounds every year.
Judge Cheryl Cole, who was joined by Will.i.am from Black Eye Peas, was filmed at the 70-bed hotel when selecting the females to go through to the live finals in 2010.
The duke and prince play regularly on Coworth Park's world class polo grounds, which are managed by Guards Polo Club, and last year Meghan watched her then boyfriend play on the pitch.
